The testimony outlined how provenance metadata can support transparency, rights signalling, and scalable licensing frameworks for creative content in generative AI pipelines.

In this talk I will contrast three provenance technologies: metadata, fingerprinting and watermarking, and discuss how they may be combined to provide robust trust signals to support stories told by real and Generative AI images. I will outline Content Credentials, an emerging standard for provenance metadata and how its rapid adoption promises to play an important role in fighting fake news and the spread of misinformation. Beyond uses in contente authenticity, I will describe how provenance can also underpin new models for value creation in the age of Generative AI. In doing so I address risks arising with generative AI such as ensuring training consent, and the proper attribution of credit to creatives who contribute their work to train generative models", "links": { "event": "https://saiconference.com/FTC" } }, { "title": "What makes Content Credentials durable?", "date": "2025-01-25", "venue": "Content Authenticity Initiative (CAI) Community Webinar", "youtubeId": "p_HKMtqkMnk", "abstract": "Presentation on Content Credentials (C2PA) and the ways in which watermarking and fingerprinting can support C2PA metadata to make it more durable as content is distributed across the internet or even printed!
